Campus smart card involves two passwords: inquiry password and consumption password, in which the inquiry password is used for information inquiry and card loss reporting on self-service terminals (such as websites, deposit machines and telephones); Consumer password is a transaction password set to ensure the security of cardholder's campus card funds. It is used for identity verification in case of over-consumption (the highest default value is 50 yuan/day), and it is also used for self-service recharge of campus one-card funds.

The inquiry password and consumption password are initially "888888" or the last six digits of the cardholder's ID card (if the last digit of the ID card is "X", it will be postponed by one digit).
